That's the "hexalator", right? Mine finally gave up the ghost from overuse.
You don't need manuals. Just poke at it until you figure it out.
IIRC, the programming codes are the row and column of the key. If the number
of digits of a result is wider than the screen there is a way to scroll
sideways. There is a key sequence to set the word width. Everything else is
either obvious (to one who has had an HP before) or written on the back.
The manual is probably in a box the attic. The kids will find it after I'm
dead.

I got the back off my dead 16C, but something is holding the PC
board into the front of the case. Isn't there one of Murphy's
laws that says that you never figure out how something comes
apart until you have broken it? I don't want to do that. How do
you get it apart?
The first thing you see once you get the back off is a hefty PC
board with the two chips on it.
I have a 34C, still working, except the ^ and x<>y key bubbles
are worn out. It used something called RSS (Roger's Solderless
System?) -- a plastic frame holds all the chips in place and
presses them against a flexi circuit. It worked OK for a while,
then I had to take it all apart and solder the chips to the
flexi. I tore out the strip of flexi that went to the battery
connector, replaced it with wire wrap wires, and cut a hole in
the side and installed a real power switch. Nasty job -- the
flexi didn't want to tin at all.

The 'voyagers' (HP10C, 11C, 12C, 15C, 16C) went through
various hardware
versions. The earliest ones have a separate logic
module built
on a
flexible PCB clamped to the display the connects to
the
keyboard via a
zebra strip connector. Later versions put everything
on one
PCB. And the
even later versions (12C only I think -- the others
having
been
discontinued by then) put everything into one chip.
The older machines contain 2 chips. The smaller one is the
'Nut' CPU.
This is very similar to the CPU used in the HP41, for
example.
The CPU
also contains the keyboard scanning circuitry.
The larger chips is called 'R2D2' (seriously!). It stands for
'ROM/RAM/Display Driver'. It's everything else. ROM containing
the
code
to make the machine behave as a 16C (or whatever). RAM
for
user programs
and data. And the LCD driver.
FWIW, Voyagers suffer from bad connections. On the separate
logic module
versions. always clean the zebra strip before doing
anything
else. If
that doesn't help, or if it's all one one PCB,
then try
resoldering the
chips (fine surface-mount connections). I've had a
lot of dry
joint
problems in this series.

After gently and unsuccessfully prying to see if I could get the
PC board out, I gave up and put it back together. I stole the
batteries out of a laser pointer and tried it, and Behold! -- it
works. Perfectly!

I looked in the attic. I found an Intel 432 architecture manual,
Occam programming manual, Fairchild F8 and Clipper blurbs, a
complete Rockwell 6502 development system, BBC Archimedes
software guide, some VAX books, a Z80 pocket reference card, an
OS/32MT pocket ref, HP2100A book, a mylar tape, a stack of punch
cards -- Nope, that's too far back. It's not here. Sorry.
I did find my dead 16C.
Here's an idea --- we could write our own manual out of our
heads. What's the LJ key do?

You used to be able to order the manual from HP. God knows whether
they provide that service now. (And they screwed up the copying of
my HP-97 manual.) I have one extra Xerox copy of the manual from HP
(I got it, then I got an original manual.)
LJ is left justify. Given a word with leading 0s, it removes them;
it also returns the number of leading 0s. Before --
x
n 0 bits, 1 bit, other stuff
After --
x y
n 1 bit, other stuff
A few other exotic operations include counting 1 bits and generating
masks. Let me know if you have more questions.

Do you need a real manual, or would a PDF be enough?
